Turgor Pressure
 Turgor
Pressure is the main pressure of
the cell contents against the cell wall in
plant cells and bacteria cells, determined
by the water, resulting from osmotic
pressure.

Plant cells
So, plant cells have a thick cell wall
surrounding the cell membrane.
Excellent.
Plant cells usually have a humongous water-filled
vacuole, called a central vacuole, that pushes out
on the cell membrane to keep the cell rigid and
tough. If the vacuole loses too much water, it will
cause the cell to become limp. If too many cells
suffer this fate, the entire plant will “wilt” and its
leaves will lose their shape and strength and
droop.
